The bottom layer is the lowest layer of a PCB board, usually also the outermost layer. The bottom layer is generally used for welding electronic components and connecting external circuits. The bottom copper foil layer is generally used to connect signal wires such as electronic components and power supplies. The bottom layer can also be printed with information such as the identification, model, and production date of the circuit board.

The inner layer is the layer between the top and bottom layers of a PCB board. The inner layer is generally used to connect signal lines and power supplies between different layers. The inner copper foil layer will not be directly exposed to the outside, but will be wrapped between the substrate layers to protect the copper foil layer from damage.
